Most brands focus on quick fixes or rely on generic probiotics that only treat symptoms. 38TERA® was founded by a board-certified gastroenterologist to address the root cause of digestive issues. We use clinically dosed, targeted ingredients — like specific prebiotic fibres and resistant starches — to feed the beneficial bacteria you already have, creating lasting, foundational health. Our products are third-party tested, clinically guided, and designed to fit effortlessly into your daily life.
Yes. Our products are designed to be a safe, effortless part of your daily routine. Every formula is rigorously third-party tested for purity and potency, and we never use artificial fillers, sweeteners, or harsh stimulant laxatives. If you have specific medical conditions, are pregnant, or are taking prescription medications, we always recommend consulting your physician before starting any new supplement.
Gut health is cumulative, not instant. While some people notice improvements in digestion and bloating within the first few days, the most meaningful benefits — like a stronger gut barrier, increased microbiome diversity, and reduced inflammation — develop over 4 to 8 weeks of consistent daily use. We set these expectations clearly because we’re in the business of lasting change, not short-term fixes.
DMN™ is a supplement activated by the gut microbiome, and therefore can cause gas and bloating symptoms in some cases as your body adjusts to taking it. It is Certified Low FODMAP, meaning that it was formulated to cause less gut symptoms than other prebiotic supplements. But it is still possible, particularly among those with a damaged gut microbiome, constipation, histamine intolerance, or other food intolerances. Please review the "DMN & your health" section in our Help Center for additional insights on these conditions. Also, it is rare, but it is possible for a person to have an allergic reaction to the ingredients in DMN™. We third party test for purity to insure that there are no contaminants, so that you can be confident that the only ingredients in a can of DMN™ are the ones seen on the package label.
